Rhino poaching increased by over 40% from 2011-2012, posing a real threat to communities and tourism operations that depend on wildlife. Over two years, ZSL plans to reduce poaching incidents in a threatened Kenyan protected area by 50%, providing greater protection for endangered rhinos, elephants, and more. Ultimately, increased awareness of effective patrols will deter poachers, reduce threats and increase security for local community groups and wildlife rangers.Get involved:Cast your vote by the 31st May on https://globalimpactchallenge.withgoogle.com/ for the £500,000 fan favourite Global Impact Award.
